G'day George,That's a rather odd bit of address ... I thought it might have been an alternative name for the old-established Cornstalk Bookshop, in Glebe Pt Rd, Glebe (since "Cornstalk" ... old local term for a native-born new South Welshman ... doesn't mean much to anybody who isn't). Jowvere, despite the Glebe PO address, The Book Firm seem to have their physical presence in Doncaster Ave, Kensington - about 6 kilometres south east. Maybe they have an office ... or a home ... in Glebe.
Anyway, I will walk past Cornstalk (with whom I have dealt a number of times) on the way home in 4 hours ... but not The Book Firm, so it's back to someone who may have dealt with them. (They are in the telephone directory, so they aren't exactly a "hole in the wall" ... maybe.)
Regards,
Bob Bolton
